ELECTRICALLY IGNITING LAWS AND LlQUlD-FUEL-BURNlNG DEVICES.

SPECIFICATION forming part of Letters Patent No. 642,804, dated. February 6, 1900.

Application filed July 30, 1898- To aZZ whom it may concern;

Be it known that 1, ROBERT SCHREIBER, a

I subject of the King of Prussia, Emperor of Germany, residing at Berlin, in the Empire of Germany, have invented a new and useful Device for Electrically Igniting Lamps and all other Liquid-Fuel-Burning Devices.

My invention relates to a device for electrically and instantaneously igniting 'any lamp or other apparatus using a liquid fuel; and it consists of the new and improved mechanism hereinafter described and set forth in such full, clear, and yet concise terms that any one familiar with the art can readily understand, construct, and use the device.

In the following specification, of which the accompanying drawings form an inseparable part and in which latter similar letters refer throughout to similar parts, I have described my invention in connection-with a lamp, as it is preferably used with that device; but I do not limit myself to such singular use. In fact, I reserve the rights and privileges of using it in combination with any liquid-burning device from time to time asI may see fit and desire.

In the accompanying drawings, Figure l is a sectional elevation of a lamp in combination with my invention. Figs. 2 and 3 show, on an enlarged scale, details of my invention.

When my invention is used in connection with a lamp, I em ployapreferably semiglobular receptacle 1), in which is placed any electrical contrivance capable of generating and maintaining an electrical current of predetermined strength. The receptacle has a removable top 6 secured thereto and which is provided with an annular depression in its upper surface. Secured to the lower surface of this top and near the center thereof is an electrode a,while surrounding the walls of the said depression and vertically movable is a second electrode f. These two electrodes form the poles of a galvanic element, as will be more clearly seen at a later point.

Above the electrical generator is an oil or fluid reservoir e, having a depending projection on its lower side fitting within the depression aforesaid. In one side of this reservoir is a vertical opening g, registering with a corresponding opening formed in the upper SerialNo. 687,299. (No model.)

outer collars, vertically-movable inner collar Z2, and a wick z therebetween. Connected with said inner collar Z2 is a rack h, which is vertically adjusted (thereby carrying said wick) through the rotation of apinion on the inner end ofarod x. (Shown in Fig.1.) Mount= ed within the said burner and moving with the rack h is a vertically-extending bar a,

which projects upwardly into a tubular support '0'. (Best shown in Fig. 1.) On the upper end of this support is a round plate or flameseparator 7', which in diameter is greater than that of the said wick, thereby preventing the flame of the latter from coming in contact at any time with an igniting-spiral t, hereinafter described, and having secured thereto a depending cylindrical perforated body 3 on which are outwardly-projecting ribs y in constant contact with the inner collar 2 of the said burner. This burner, as will be clearly understood, is in metallic contact with the upper surface of the said reservoir, which in turn is in metallic contact with post 0 aforesaid. Firmlyengagingthesaid body'yandextending upwardly a predetermined distance is a wire Z, having an igniting spiral t, preferably of platinum or the like, secured to its up per end. Extending parallel with said wire is a second wire la, having its upper end connected with the other end of the said spiral and extending downwardly below said body, where it is fastened to a jacket 1), firmly mounted upon, but insulated from,the tubular supportiaforesaid. Properly fastened to and insulated from the said burner is a spring 8, bearing constantly against the said jacket and having its lower end in metallic contact with insulated conductors 0 and 10, running through the top of said reservoir and engage ing directly or indirectly or through any desired medium, such as conductor 1;, the elec* trode a aforesaid. I

The operation of my invention will be clearly understood from the foregoing de scription and accompanying drawings when taken in connection with the following statement:

The parts being assembled in the manner described and it being desired to ignite the wick,the postc is pressed downwardly,whence the electrode fis submerged or brought in contact with the generator, whence the electrical current fiows from the electrode a through conductor v and into conductor 10, from whence it passes through conductor 0 upward through springs into jacket p,which in turn conducts the current to wire it, from the upper end of which it passes through the platinum spiral t, producing here such a diffusion and radiation of heat that the wick is ignited. Leaving the spiral it passes through wire Z into the cylindrical body 3 described and from thence through the burner into the metallic top of said reservoir, from which it is collected by post 0 and returned through the electrode f to the starting-point.

It will be clearly seen and particular attention is called tothe fact that notwithstanding any vertical adjustment of the wick the position of the igniting-spiral relative to the upper edge of the wick remains invariable. According to this the igniting process may be effectuated in each position of the wick.

The tubular support 71, with its cylindrical perforated body 3 being held in place only by friction on the bar it it is obvious that it may be turned around the said bar, the igniting-spiral tcoming thus in position with each point of the periphery of the wick. It is consequently possible to alter at will the igniting-point.

If desired, a tubular extinguisher n, operated by lever 72, may be mounted on the burner, as shown, though the same forms no part of the present invention.

Having now described my invention, what I claim as new,and desire to protect by Letters Patent, is-

1. In a device for, igniting the wick of a liquid-burner, the combination of an ignitingspiral near the upper edge of the lamp-wick, means for raising and lowering the same together with the wick, an electrical generator, conductors connecting said spiral and generator, and means for sending a current therethrough, substantially as set forth.

2. In a device for igniting the wick of a liquid-burner, the combination of an ignitingspiral near the upper edge of the lamp-Wick, a carrier for said spiral, a vertically-adjustable rack for raising and lowering the lampwick, means for connecting said carrier with said rack, an electrical generator, conductors connecting said spiral and generator, and means for sending acurrent therethrough, substantially as set forth.

3. In a device for igniting the wick of a 1iquid-bur11er, the combination of an ignitingspiral near the upper edge of the lamp-wick, a carrier for said spiral, a vertically-adjustable rack for raising and lowering the lamp- Wick, a vertically-extending bar on the upper end of said rack, a tubular support in said carrier carried by and adjustably supported on said bar, an insulated jacket on the tubular support,conductors connecting the ends of said spiral with said carrier and jacket, an electrical generator, conductors connecting said carrierandjacket with the generator,and means for sending-a current therethrough, substantially as set forth.

4. In a device for igniting the wick of a liquid-burner, the combination bf an ignitingspiral near the upper edge of the lamp-wick, a carrier for said spiral, a vertically-adjustable rack for raising and lowering the lampwick, a vertically-extending bar on the upper end of said rack, a tubular support in said carrier carried by and adjustable on said bar, a flame-separator, an insulated jacket on said tubular support, conductors connecting the ends of said spiral with said carrier and jacket, an electrical generator, conductors connecting said carrier and jacket with the generator, and means for sending a current there.

through, substantially as set forth.

5. In a device for igniting the wick of a liquid-burner, the combination of an ignitingspiral near the upper edge of the lamp-wick, a carrier for said spiral, a vertically-adjust able rack for raising and lowering the lampwick, a vertically-extending bar on the upper end of said rack, a tubular support in said carrier carried by and adjustable on said bar,

a flame-separator, an insulated jacket on said tubular support, a burnerin metallic contact with said carrier, a spring connected with said burner and insulated therefrom and bearing on said jacket, an electrical generator, conductors connecting said generator with said burner and spring, and means for sending a current therethrough, substantially as set forth.

In testimony whereof I have hereunto set my hand this 23d day of May, 1898.
